SWING-OPERATED MOTOR.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed. February 18, 1911. Serial No. 609,374.

To all whom it may concern: 4 Be it known that I, EDWARD Loonn, a citizen of the United States, residing at Clifton:

dale, in the county of Essex and State of Massachusettahave invented certain new and useful Improvements in Swing-Operated Motors, of which the following is a specification.

This invention relates to swing operated motors and the object of the invention is to provide a simple and effective device of this character by which reciprocatory motion can be converted into rotary on both strokes of the reciprocatory member of whatever character the same may be. From the statement just made it will be evident that this reciprooatory member may vary greatly in type. I have found that I can satisfactorily and with advantage utilize the platform of a swing for this purpose.

In the drawings accompanying and forming part of the present specification I have illustrated in detail one convenient and advantageous form of embodiment of the invention which to enable those skilled in the art to practice the invention will be set forth in detail in the following description while the novelty of the invention will be included in the claim succeeding said description. From such observations it will be apparent that I do not limit myself to the showing made by said drawings and description. I may depart therefrom in several respects within the scope of the invention expressed in said claim.

Referring to said drawings: Figure 1 is a side elevation of a platform swing having associated therewith power transferring mechanism comprising my invention. Fig. 2 is a transverse section on the line 22 of Fig. 1, and, Fig. 3 is a side elevation partly in section of the parts shown in Fig. 2.

Like characters refer to like parts throughout the several views, which it will be seen are on different scales.

The apparatus involves in its make-up a shaft as 2 and said shaft may be properly considered the power shaft as it is from the same that the power necessary to drive various machines may be taken. This shaft is shown supported by bearings 3 and as loosely carrying the substantially duplicate gears 4 and 5. Said gears are adapted to be intermittently coupled with the shaft 2 in any suitable way, for example and as 'shown by pawl and ratchet mechanisms, the

ratchet-wheels being denoted by 6 and 7 and the respective cooperating pawls by 8 and 9. Said ratchet-wheels are fastened to said shaft in some desirable manner, for instance by being pinned or keyed thereto. The pawl 8 is pivotally supported by the gear 4'while the pawl 9 is similarly carried bythegear 5. As will hereinafter appear these gears are positively operated by rack means, one of them directly and the other through an intermediate gear; I might state at this point that said gears are alternately operated in opposite directions, each gear when turned one way serving through the pawl and ratchet or equivalent means, to rotate the shaft 2 while when it is turned in the opposite direction, it is inefiective as a power-transmitting factor. The active movement of the gears, however, is in the same direction being illustrated by the arrow on the gear 4. When said gear is turning in said direction, the pawl 8 is revolved therewith and serves to rotate the ratchet wheel 6 and consequently the shaft 2. During this action the gear 5 is being oppositely rotated and the pawl 9 thereon rides idly over the teeth of the ratchet-wheel 7. Located in a different level from the coaxial gears 4 and 5 is a pinion 10 which in the present case is situated above said two gears 4 and 5 being supported by a bearing as 11. The pinion 10 is in mesh with the gear 5.

As before intimated there is a reciprocatory member and the platform 12 of a swing serves advantageously in this connection, its effect being transferred alternately to the gears 4 and 5 already described, in conjunction with racks as 13 and 14, the rack 13 being in mesh directly with the gear or pinion 4 while the companion rack 14 is in mesh with the pinion 10. These racks as will be evident are in parallelism although the rack 14 is slightly higher than the rack 13. They are shown integral and as provided with a base 15 adapted to be received by ways as 16 which guide said racks for reciprocatory movement in a straight path. I have shown the rack means as operatively connected with the reciprocatory member 12 and for this purpose the pitman or connecting rod 17 may be provided. It will be assumed that the two racks are moving in the direction of the arrow applied to the rack 13. In this case said rack 13 will rotate the gear 4 in the direction of the arrow marked thereon so that the pawl 8 will turn the ratchet wheel 6 and the latter in turn rotate the shaft 2. During this period the pinion 10 is being rotated in the same direction as the gear 4: and as the said pinion 10 is in mesh with the gear 5 it follows that the latter will be rotated oppositely to the gear 4 whereby the pawl 9 will ride idly over the teeth of the ratchet-wheel 7 and it therefore follows that the effect of said ratchet-wheel 7 at this time will not be applied to the shaft 2. On the return movement of the rack means, however, the operation described will be reversed; that is to say the gear 5 will be turned in such direction as to cause the pawl 9 to rotate the ratchet-wheel 7 and hence the shaft 2 in the same direction that it had been turned by the ratchet-wheel 6. While therefore the reciprocatory member 12 is in action the shaft 2 will be continuously rotated. It is not essential that the two racks be straight; they may be of any convenient form and in some cases can be connected directly with the platform.

What I claim is:

The combination of a supporting frame, a swinging member carried by said frame, a pair of rigidly connected racks facing in the same direction, link means operatively connecting the swinging member and racks, for reciprocating said racks on the swing of said swinging member, means carried by said supporting frame for positively guiding the racks in a predetermined path, a rotary shaft, a pair of gears loosely supported by said shaft, one of said gears being in mesh with one of said racks, a pinion in mesh with the other gear and with the other rack and means for transferring the effect of said loosely supported gears to said shaft when they are successively rotated.

In testimony whereof I aflix my signature in presence of two witnesses.

EDWARD LOCKE.
